NuTyX is not a multi-lib

It takes much more time to build up a multilib distribution.
Normally all the libraries need to be compiled in 64 and 32 bits.

Today, it's not possible to produce a multilib because there are links created at construction / installation of NuTyX (lib64->lib) under /lib and /usr.

The installer doesn't allow me to specify a separate /home partition

This question has been asked many times.
I will try to answer it as clearly as possible.

Modern users often have a lot of data on their computers.
The size of the home folder can quickly become very large.
MP3 files, photos and videos are big files.

Imagine that you have a 250 GB hard disk.
You say "OK, I'll take 100 GB for the system and 150 GB for my personal data."
Great! You just cut your disk into two pieces, and the home partition will fill up more quickly in proportion to its size than if you had retained a single partition.
It would be nice if we could reinstall NuTyX when we wanted without having to cut the hard disk into separate partitions to preserve personal data.
That's exactly how the NuTyX installer works.

The installer will never format a partition that is already formated, without manual intervention.

If you have a distribution (NuTyX or any other) with personal data and the system on the same partition,
the installer will tell you during the installation process that there is already a distribution there but will not offer to format the partition.
You will need to delete the /var, /proc, /sys, /usr, /sbin, and /etc folders, but other folders such as /home and /MP3 will not be touched.
So your data are safe.

Today it is very easy to configure a file server based on NFS, so that users could have their home folders on a remote server.

To summarise: creating a separate home partition today is unecessary, at least with NuTyX.
It's worth asking why Apple's MacOS operating system never recommended this.

Building packages in a chroot. When and Why ?

The NuTyX ISOs install a base system which gives the user a choice between two scenarios in using the distribution:

NuTyX can be considered as a "binaries" distribution.

The user installs the needed binary packages by downloading them from the remote server.

Once the base system is installed, the user installs their favourite applications as explained in the online documentation.
